What is the main difference between an equation and an inequality?

An equation shows when two things are equal, while an inequality shows when two things are not equal.

Explain how to graph the inequality x < 3 on a number line. Be sure to explain what kind of dot you would use.

Draw a number line, place an open circle at 3, and draw a line to the left of 3 with an arrow at the end.

A speed limit on a road (e.g., speed ≤ 65 mph) or the minimum age to ride a roller coaster (e.g., age ≥ 12).

I can solve inequalities and graph the solutions on a number line.

1
Inequalities are mathematical comparisons that show when values are not equal, using symbols like 'greater than' and 'less than'.
2
When graphing an inequality like n > 3 on a number line, a(n) open dot indicates the boundary value is not included, while a(n) closed dot means it is included.
3
A compound inequality defines a relationship between a variable and two numbers, specifying a range of values between those two numbers.
